SUPPORT AND TIE FOR CONCRETE-REINFOECING BARS.

Specification of Letters Patent.

- Patented Feb. 10,1914.

Application filed April 4, 1913. Serial No. 758,837.

To all whom it may concern Be itknown that I, GEORGE E. SoHonN- THALER, a citizen of the United States, residing at Chicago, county of Cook, Illinois, have invented a certain new and useful Improvement in Supports and- Ties for Concrete-Reinforcing Bars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates generally to reinforced concrete construction, and more particularly to a simple support and tie for the metal rods used in reinforcing concrete floors, ceilings-and like structures. v

y'present invention relates to and is an improvement upon the support and tie disclosed in my pending application Serial #597,510, filed December 15, 1910.

In reinforcing concrete floor and ceiling construction it is desirable and in some instances essential that the reinforcing rods be supported in a plane above the temporary flooringv or form upon which the concrete is laid, and it is the principal object of my invention to provide a simple, strong and inexpensive one-piece support which can be readily positioned on the temporary floor or form, and which will maintain the reinforcing rods a substantial distance above said floor or form while the plastic material is being poured or distributed thereupon.

Further objects of my invention are, to provide a simple, one-piece device particularly adapted for supporting and tying together reinforcing rods which are arranged substantially at right angles to each other,

to form .points on the base of the combined support and tie, which points are adapted to engage the temporary flooring in such a manner as to firmly hold the support and tie in place, and to form a support and tie with one or more upwardly projecting prongs or fingers which can be readily bent around one of the reinforcing rods, thereby practically tying said rod to the rod which is engaged and supported by the main body or base of the device.

With the above and other objects in view, my invention consists in certain novel features of construction and arrangement of parts hereinafter more fully described,

claimed and illustrated in mg drawings, in which:

F igure 1 is a perspective View of a comthe accompanybined concrete reinforcing bar support and tie of my improved construction. Fig. 2 is a vertical section taken through the center will be noted that the support and tie is formedof a single piece of sheet metal, the main body portion of which is bent into inverted V-shape so as to form a pair of i11 clined legs 10 and 11,- and the upper portions of these legs are slotted, as designated by 12. The ends of the slot 12 are preferably rounded, as designated by 13, in order to form seats for a reinforcing bar or rod A. The lower end of the leg 11 is notched or cut away, as designated by 14, which construction readily permits the concrete, while in plastic condition, to flow freely beneath the main body portion of said leg, and said construction also forms points 15 at the lower corners of said leg 11, which points tend to engage the temporary flooring or support upon which the floor or ceiling is formed, thereby anchoring the support and tie while the concrete is being poured onto said flooring around the reinforcing rods. Formed integral with the lower end of the leg 10 is an upwardly projecting leg 16, the upper portion of which'isslotted'to form a pair of prongs or projections 16 which are adapted to be bent downward partially around areinforcing rod B which is posi tioned on top of the rod or bar A, and arranged substantially at right angles thereto.

hen a device constructed as just descri ed is associated with a pair of crossed reinforcing rods, the lower rod A rests upon the seats13. and passes through the slot in the plate 16, and-the rod B occupies a position between the upper portion of the leg 10 and the prongs or fingers 16*}, although, if desired, said rod B can be arranged outside V the pron s lines in d or. fingers 16*, as shown by dotted ig. 2. When the upper ends of the prongs or fingers 16 are bent downward to engage the rod B, the two rods are effectually tied together, and-they are supported in a firm and substantial manner a suitable distance above the temporary flooring on which the floor or ceiling is formed. The rounded lower end of the slot in the plate 16 is seats 13 and thus the different points on the support and tie.

In thetconstruction' illustrated in Figs. 3 and 4 the main body of the device comprises a rectangular plate of sheet metal bent into inverted V-shape to form a pair of inclined legs 18 and 19, the upper portions of said legs being slotted to form seats 20 for the in horizontal alinement with the lower one of a pair of crossed reinforcing rods, and the lower ends of the legs 18 are notched, as designated by21, to form anchoring points. 22, and for the purpose. of permitting the plastic concrete to flow freely into the space between said legs. In this form of the device one of the legs 18 is made slightly wider than the opposite leg, and formed integral with the side portions of this wide leg is a pair of upwardly projecting prongs or fingers 23 which are adapted to be bent downward over the upper one of the reinforcing rods, as shown in Fig, 4, and which upper rod rests upon and occu= pies a position substantially at right angles 4 to the lower rod, which latter rests upon the seats 20.

I Combined supports and ties of my improved construction are simple, strong and durable, can be made in various sizesso as to accommodate reinforcing rods of diiferent diameters, and said devices can be very cheaply produced inasmuch as they can be readily stamped from large sheets of metal, and bent into shape at the same time they are stamped out.

I do not desire to limit myself to the'exact details of construction herein shown and described, for obviously minor rod A rests at three inclined legs mama's form and construction may be resorted to without departing from the nature and principle of my invention, the scope of which is set forth in the appended claims.

I claim:

1. A device of the class described comprising a metal plate bent transversely into V-shape so as to form a'pair of inclined legs, the upper portions of which legs are slotted to form a pair of oppositely disposed seats adapted to receive a reinforcing rod, means integral with one of the and projecting upwardly therefrom on opposite sides of the seat in said leg for engaging a second reinforcing rod which is arranged substantially at right angles to the first mentioned rod, and one of said legs being provided at its lower' end with a pair of points which are adapted to engage the surface on which the device is positioned.

2. A device of the'class described'comprising a metal plate bent transversely into V-shape so as legs, the upper portions of which legs are slotted to form apair of oppositely dis posed' seatsadapted to receive a reinforcing rod, means integral with one of the inclined legs and projecting upwardly therefrom on opposite sides of the seat in said which is arranged substantially at right angles to the first mentioned rod, and the lower end of one of said legs being notched to permit concrete to flow beneath said leg ehaniglesin to form a pair of lnclined leg for engaging a second reinforcing rod and also, to form a'pair of anchoring points on said leg, which points engage? the surface on which the device is-positioned.

In testimony whereofI hereunto aflii; my signature in the presence of two witnesses, this-29th day of March, 1913, y i Q I GEORGE E. SGHOENTHALER';
